SHIMANO, magnetic brake for 17, 21 Ocea Jigger (1000, 1500, 2000) reels. This is a magnetic brake for converting to a Jigger casting specification. This is a powerful part for serious bait jigging anglers. I bought it for light jigging on a boat, but I'm selling it because I don't use it. With this part, you can handle both shore jigging and offshore jigging, so it's a great deal. Although it is unused, please understand that it is a used item. No claims, no returns. #MagneticBrake #OceaJigger #Jigging #ShoreJigging #OffshoreJigging
